Fetal movement refers to motion of a fetus caused by its own muscle activity. Locomotor activity begins during the late embryological stage and changes in nature throughout development. Muscles begin to move as soon as they are innervated. These first movements are not reflexive, but arise from self-generated nerve impulses originating in the ...
A woman's uterine muscles, rather than her abdominal muscles, are first to sense fetal motion. Therefore, her body weight usually does not have a substantial effect on when movements are initially perceived. Women who have previously given birth have more relaxed uterine muscles which are more sensitive to fetal motion during subsequent ...
Women are 4-5 times more likely to develop a clot during pregnancy and in the postpartum period than when they are not pregnant. [25] Hypercoagulability in pregnancy likely evolved to protect women from hemorrhage at the time of miscarriage or childbirth. In developing countries, the leading cause of maternal death is still hemorrhage. [25]
A decrease or cessation in sensations of fetal activity may be an indication of fetal distress or death, [31] [32] Still, medical examination, including a nonstress test, is recommended in the event of any type of any change in the strength or frequency of fetal movement, especially a complete cease; most midwives and obstetricians recommend ...
A woman pregnant for the first time (nulliparous) typically feels fetal movements at about 21 weeks, whereas a woman who has given birth before will typically feel movements by 20 weeks. [13] By the end of the fifth month, the fetus is about 20 cm (8 in) long.
A spontaneous vaginal delivery (SVD) occurs when a pregnant woman goes into labor without the use of drugs or techniques to induce labor and delivers their baby without forceps, vacuum extraction, or a cesarean section. [1] An induced vaginal delivery is a delivery involving labor induction, where drugs or manual techniques are used to initiate ...
This process is called differentiation, which produces the varied cell types (such as blood cells, kidney cells, and nerve cells). A spontaneous abortion, or miscarriage, in the first trimester of pregnancy is usually [8] due to major genetic mistakes or abnormalities in the developing embryo. During this critical period the developing embryo ...
Fetal programming, also known as prenatal programming, is the theory that environmental cues experienced during fetal development play a seminal role in determining health trajectories across the lifespan. Three main forms of programming that occur due to changes in the maternal environment are:
